Abstract

L’invention concerne une pièce pour un dégazeur centrifuge d’un mélange air/huile de turbomachine, destinée à tourner autour d’un axe longitudinal de symétrie, formant une enceinte annulaire de séparation centrifuge dudit mélange, l’enceinte formant une veine de passage de fluide dont une entrée est orientée axialement pour l’alimentation de l’enceinte avec ledit mélange, et dont une première sortie est orientée radialement vers l’intérieur pour la sortie de l’air déshuilé séparé dudit mélange, l’enceinte comportant en outre une paroi périphérique (3b) extérieure de forme générale cylindrique percée d’une pluralité d’orifices (8), destinés à évacuer l’huile séparée dudit mélange vers l’extérieur du dégazeur, caractérisée en ce que la surface radialement interne de ladite paroi périphérique (3b) comporte des motifs en creux connectés à l’embouchure desdits orifices (8), de manière à drainer l’huile recueillie par ladite paroi périphérique vers lesdits orifices.
